This is on the back of a £2.2bn bid for AWG, which owns Anglian Water.

Meanwhile, Man Group is up 1.9% to 456.5p, although the gains have been limited by Prudential which is down 1.66% to 652.5p, after the company - whose shares jumped on Friday on takeover talk - said it is examining its options for its UK operation.
